This paper discusses design, manufacture, and control concepts for antennas that employ programmable features. ABSTRACT | The advancement in wireless communications requires the integration of multiple radios into a single platform to maximize connectivity. In this paper, the design process of reconfigurable antennas is discussed. Reconfigurable antennas… (More)
— Waterfilling solutions provide optimal power distribution in multiple-input multiple-output (MIMO) system design. However, the optimal distribution is usually obtained through costly computational processes, such as the determination of the system eigenvalues. For communication channels in a fast paced environment, the costs are even higher due to the… (More)
This paper introduces the modeling of reconfigurable antennas using graphs. Several examples are presented and analyzed. Graphs are shown herein to be useful for modeling reconfigurable antennas with different techniques and properties.
Differential Interferometry (D-InSAR) is a technique that estimates terrain movements at the sub-wavelength scale using repeat-pass interferometry. In order to obtain such precision, the phase errors due to motion (uncorrelated for each pass) shall be known and compensated also within this accuracy. For airborne systems this becomes a challenging task due… (More)
